I know that some free blogs wont let you post advertisements on your blog so making money is virtually impossible. I just finished my free blog site where you can sign up if you want...
Sailblogging.
My goal was to keep HTML options open to all bloggers, and eventually put a designated space for you to possibly post your adsense banner. I love having this site, but my goal is to meet the BLOGGERS feedback. I want to build the perfect blog hosting site based on the BLOGGERS...
I have kept my ads dormant for the time being to see how the site goes first. But if you are looking for a blog where you can post your advertisements IN THE BLOG to make money, I recommend signing up for a blog... it is free, and its userbased, so just leave me a comment if you need something changed or wanna recommend something
Thanks for readin, i know its long haha...
